A legend in bowling. A very sad loss, 52 is a young age for a great sportsman. RIP Edit. I remember watching this and thought, how the f what the hell? How did it ... I think everyone did

I have no idea how and what to do.

You don't need to be good at bowling if you're good at engineering.

For part a I used conservation of energy. -m*g*cos(θ)*L+1/2*m*0^2=-m*g*L +1/2*m*v^2 => v = sqrt(2*g*L(1-cos(θ )). b) For b I was think that T = mg in the equilibrium point but that doesn't invole θ in the answer. So that's why I tought that T*cos(θ ) = mg. So that the tension is mg/cos(θ). But...

In a recent thread we discussed the idea that an object slowly dropped into a black hole, can have its rest mass recovered, as energy, if slowly brought to a halt at the event horizon. Once the object is dropped, it would be unrecoverable, and the BH would gain no new mass. I am under the...

I already have a and b, but want to see if anyone is willing to verify my answer for part c. I get 0 for the frictional force between the ground and ball, which would lead d and e to be 0 as well. Physics is rarely that easy so I wanted to make sure I didn’t miss anything.

Homework Statement Say you're bowling and you roll the ball down the lane. The bowling ball has just knocked the first bowling pin forward and that pin's forward velocity is now much larger than the bowling ball's velocity before their impact. How can the pin travel forward faster than the ball...

Hi there! I chanced upon this problem whilst trying to brush up my Classical Mech knowledge and found it confusing. Hope someone out there can provide an insight! Homework Statement A bowling ball of mass m and radius R sits on the smooth floor of a subway car. If the car has a horizontal...

Ok so a ball starts moving to the left while the rotation is clockwise, hence the backspin. On this surface there is friction. So clearly as the ball moves to the left, there is Kinetic friction to the right slowing down the Vcm and the spin as well. So assuming that the initial backspin is...

I have been doing a lot of reading online concerning this circuit but having little luck in my dilemma. I work in the bowling industry the machines use 1/3 HP 115 v single phase induction motors. FLA on these motors is 6 Amp. These motors use capacitors 480-520 MF for braking. This braking...

Hi, new here, so I hope I'm doing this correctly. I'll keep this question as brief as possible, but it requires just a bit of setup. I'm not an engineer or physicist, but do have a more than decent layman's understanding. I've lately become fixated on the game of bowling (ten pin), and have...

A bowling ball is released with no rotation (linear KE only) at a given speed, the friction between the ball and the lane creates a torque which tends to rotationaly accelerate the ball, robbing it of linear KE and reducing the linear speed until synchronous speed is reached. My question is ...

Hi everyone, this problem involves smooth rolling and translational motion: 1. Homework Statement A bowler throws a bowling ball of radius R= 11 cm along a lane. The ball slides on the lane with initial speed vcom = 8.5 m/s and initial angular speed w0 = 0. The coefficient of kinetic friction...

In bowling, the ball will have a heavy spot marked as the center of gravity (cg). This will have an additional 1oz to 5 oz of weight to compensate for when the fingers are drilled into the ball. In bowling a dodo scale is used to measure the difference in static weight of the bowling ball...

Ok so when one drops a bowling ball hanging from a rope, it won't come back and smack him in the face. This I can understand, due to potential energy of gravity and conservation of energy. However when someone pushes the bowling ball, how can you show that it will rise higher than the original...
